3 Product description
Scope of delivery
The scope of delivery encompasses:
Application area
The radar sensor VEGAPULS WL 61 is the ideal sensor for all applications in the water and waste water industry. It is particularly suitable
for level measurement in water treatment, in pump stations as well as
storm water overflow tanks, for flow measurement in open flumes and
for gauge measurement.
Functional principle
The antenna of the radar sensor emits short radar pulses with a
duration of approx. 1 ns. These pulses are reflected by the product
and received by the antenna as echoes. The transit time of the radar
pulses from emission to reception is proportional to the distance and
hence to the level. The determined level is converted into an appropriate output signal and outputted as measured value.
Packaging
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
according to DIN EN 24180.

Instructions for installation
For tight installation of the version with plastic horn antenna with compression or adapter flange, the following conditions must be fulfilled:
1. Use suitable flat seal, e.g. of EPDM with Shore hardness 25 or 50
2. Make sure the number of flange screws corresponds to the number of flange holes
3. Tighten all screws with the torque stated in the technical data
Polarisation plane
The emitted radar impulses of the radar sensor are electromagnetic
waves. The polarisation plane is the direction of the electrical wave
component. By turning the instrument in the connection flange or
mounting strap, the polarisation can be used to reduce the effects of
false echoes.
14
VEGAPULS WL 61 • 4 … 20 mA/HART - two-wire

The position of the polarisation level is marked by marking bars on the
instrument.
4 Mounting

Installation position
Marking bar
When mounting the sensor, keep a distance of at least 200 mm
(7.874 in) to the vessel wall. If the sensor is installed in the center of
dished or round vessel tops, multiple echoes can arise. These can,
however, be suppressed by an appropriate adjustment (see chapter
"Setup").
If you cannot keep this distance you should carry out a false echo
storage before setup. This applies mainly if buildup on the vessel wall
is expected. In this case, we recommend repeating a false echo storage later with existing buildup.
> 200 mm
(7.87")
Fig. 10: Mounting of the radar sensor on round vessel tops
38061-EN-140407
In vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel, as measurement is then possible
down to the lowest point of the vessel bottom.

Socket
Approximate values of the socket heights are shown in the following
illustration. The socket end should be smooth and burr-free, if possible also rounded. After mounting, you have to carry out a false signal
memory during the parameter adjustment.

Sensor orientation
Direct the sensor as perpendicular as possible to the product surface
to achieve optimum measurement results.
Fig. 14: Orientation of the sensor
Vessel installations
The mounting location of the radar sensor should be a place where no
other equipment or fixtures cross the path of the microwave signals.
Vessel installations, such as e.g. ladders, limit switches, heating spirals, struts, etc., can cause false echoes and impair the useful echo.
Make sure when planning your measuring site that the radar sensor
has a "clear view" to the measured product.
In case of existing vessel installations, a false echo storage should be
carried out during setup.
38061-EN-140407
If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.
Small, inclined sheet metal baffles above the installations scatter the
radar signals and prevent direct interfering reflections.

Foam generation
Through the action of filling, stirring and other processes in the vessel,
compact foams that considerably damp the emitted signals may form
on the product surface.
If foams are causing measurement errors, the biggest possible radar
antennas, the electronics with increased sensitivity or low frequency
radar sensors (C band) should be used.
As an alternative, sensors with guided microwave can be used. These
are unaffected by foam generation and are best suited for such applications.

Connecting to power supply
5.1
Preparing the connection
Always keep in mind the following safety instructions:
•
•
Connect only in the complete absence of line voltage
If overvoltage surges are expected, overvoltage arresters should
be installed
Power supply and current signal are carried on the same two-wire
cable. The voltage supply range can differ depending on the instrument version.
The data for power supply are specified in chapter "Technical data".
Provide a reliable separation between the supply circuit and the
mains circuits according to DIN VDE 0106 part 101.
Keep in mind the following additional factors that influence the operating voltage:
•
•
Connection cable
Output voltage of the power supply unit can be lower under nominal load (with a sensor current of 20.5 mA or 22 mA in case of fault
message)
Influence of additional instruments in the circuit (see load values in
chapter "Technical data")
The instrument is connected with standard two-wire cable without
screen. If electromagnetic interference is expected which is above the
test values of EN 61326-1 for industrial areas, screened cable should
be used.
For instruments with housing and cable gland, use cable with round
cross-section. A cable outer diameter of 5 … 9 mm (0.2 … 0.35 in)
ensures the seal effect of the cable gland. If you are using cable with
a different diameter, exchange the seal or use a suitable cable gland.
We generally recommend the use of screened cable for HART multidrop mode.

Parameter adjustment with PACTware
For parameter adjustment of the sensor via a Windows PC, the configuration software PACTware and a suitable instrument driver (DTM)
according to FDT standard are required. The up-to-date PACTware
version as well as all available DTMs are compiled in a DTM Collection. The DTMs can also be integrated into other frame applications
according to FDT standard.
Note:
To ensure that all instrument functions are supported, you should
always use the latest DTM Collection. Furthermore, not all described
functions are included in older firmware versions. You can download
the latest instrument software from our homepage. A description of
the update procedure is also available in the Internet.
Further setup steps are described in the operating instructions manual "DTM Collection/PACTware" attached to each DTM Collection and
which can also be downloaded from the Internet. Detailed descriptions are available in the online help of PACTware and the DTMs.

Fig. 22: Example of a DTM view
Since a radar sensor is a distance measuring instrument, the distance
from the sensor to the product surface is measured. For indication of
the real level, an allocation of the measured distance to the percentage height must be carried out. To perform the adjustment, enter the
distance with full and empty vessel, see the following example:

Min. level = max. meas. distance
Max. level = min. meas. distance
If these values are not known, an adjustment with the distances of for
example 10 % and 90 % is possible. Starting point for these distance
specifications is always the seal surface of the thread or flange. By
means of these settings, the real level will be calculated.
The real product level during this adjustment is not important, because the min./max. adjustment is always carried out without changing the product level. These settings can be made ahead of time
without the instrument having to be installed.
Standard/Full version
All device DTMs are available as a free-of-charge standard version
and as a full version that must be purchased. In the standard version,
all functions for complete setup are already included. An assistant for
simple project configuration simplifies the adjustment considerably.
Saving/printing the project as well as import/export functions are also
part of the standard version.
The standard version is available as a download under
www.vega.com/downloads and "Software". The full version is available on CD from the agency serving you.

Measured value and event memory
If the device is used correctly, no maintenance is required in normal
operation.
The instrument has several memories which are available for diagnosis purposes. The data remain even with voltage interruption.
Measured value memory
Up to 60,000 measured values can be stored in the sensor in a ring
memory. Each entry contains date/time as well as the respective
measured value. Storable values are for example:
•
•
•
•
•
•
•
•
Distance
Filling height
Percentage value
Lin. percent
Scaled
Current value
Meas. reliability
Electronics temperature
When the instrument is shipped, the measured value memory is
active and stores distance, measurement certainty and electronics
temperature every 3 minutes.
The requested values and recording conditions are set via a PC with
PACTware/DTM or the control system with EDD. Data are thus read
out and also reset.
Event memory
Up to 500 events are automatically stored with a time stamp in the
sensor (non-deletable). Each entry contains date/time, event type,
event description and value. Event types are for example:
•
•
•
•
Modification of a parameter
Switching on and off times
Status messages (according to NE 107)
Error messages (according to NE 107)
The data are read out via a PC with PACTware/DTM or the control
system with EDD.
38061-EN-140407
Echo curve memory
The echo curves are stored with date and time and the corresponding
echo data. The memory is divided into two sections:
Echo curve of the setup: This is used as reference echo curve for
the measurement conditions during setup. Changes in the measurement conditions during operation or buildup on the sensor can thus
be recognized. The echo curve of the setup is stored via:

the following tables there are more detailed error messages available
under the menu item "Diagnostics" via the indicating and adjustment
module, PACTware/DTM and EDD.
Status messages
The status messages are classified in the following categories:
•
•
•
•
Failure
Function check
Out of specification
Maintenance requirement
and explained by pictographs:
Fig. 24: Pictograms of the status messages
Failure - red
Function check - orange
Out of specification - yellow
Maintenance - blue
Failure: Due to a malfunction in the instrument, a failure message is
outputted.
This status message is always active. It cannot be deactivated by the
user.
Function check: The instrument is in operation, the measured value
is temporarily invalid (for example during simulation).
This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.
Out of specification: The measured value is unstable because the
instrument specification is exceeded (e.g. electronics temperature).
Maintenance: Due to external influences, the instrument function
is limited. The measurement is affected, but the measured value is
still valid. Plan in maintenance for the instrument because a failure is
expected in the near future (e.g. due to buildup).

Rectify faults
Reaction when malfunctions occur
The operator of the system is responsible for taking suitable measures to rectify faults.
Procedure for fault rectification
The first measures are:
•
•
•
Evaluation of fault messages, for example via the indicating and
adjustment module
Checking the output signal with 4 … 20 mA instruments
Treatment of measurement errors
Further comprehensive diagnostics options offer a PC with the software PACTware and the suitable DTM. In many cases, the reasons
can be determined in this way and faults can be rectified.
